If I had to remove one novel from the Four Great Classics, I would choose Dream of the Red Chamber. Although 'Dream of the Red Chamber' was also a very important novel, its content was rather complicated and the plot was also rather complicated. It might make some readers feel that it was difficult to understand. In addition,'Dream of the Red Chamber' also had some bad content, such as descriptions of exploitation and oppression, which might be disliked by some people. Therefore, if I had to remove a novel, I would choose Dream of the Red Chamber.
